From time to time I listen to my old CD collection. However, most of the CD boxes, meaning the covers, are so full of dust that one can hardly see the image. Taste changes with the age, that is known.The sky was dark blue and this is what my sister had told me many years ago when she was there. One of the reasons for that was the altitude of the city, I recall to be it above 2000 meters.San Telmo and Bocca were two additional neighborhoods that we have visited and these were actually quite nice. We were warned by the staff of our hotel to be alert in these neighborhoods as there were many thieves.
